thirteen songs that was eventually released in late February 2014 for what turned out to be a two-part 100th episode contained eight songs from the original thirty-song list, not ten. One of those songs is Journey's "Don't Stop Believin', which was filmed on February 24, 2014, the day that the 100th episode was celebrated on set. A number of former main characters on the show have returned for this two-part episode. These include Yale student Quinn Fabray (Dianna Agron), MIT student Brittany Pierce (Heather Morris), Airman Noah "Puck" Puckerman (Mark Salling), UCLA student and aspiring singer Mercedes Jones (Amber Riley), and Joffrey Ballet School student Mike Chang (Harry Shum, Jr.). Two characters played by special guest stars return as well: April Rhodes (Kristin Chenoweth), who went to Broadway to star in an original musical that won at least one Tony award, and substitute teacher Holly Holliday (Gwyneth Paltrow). A recurring character in this episode is cheerleader Becky Jackson (Lauren Potter). An album, Glee: The Music, Celebrating 100 Episodes was released with thirteen songs on it, featuring music from both this episode and the previous one (its first part). The full album was released on March 25, 2014, and includes the six songs from this episode. Two of these songs are new covers of songs that have previously appeared on Glee: the original song "Loser like Me" performed by Darren Criss, Kevin McHale, Chord Overstreet and Jenna Ushkowitz; and a new version of Journey's "Don't Stop Believin' that features Lea Michele, Morrison, Criss, Chris Colfer, McHale and Ushkowitz. The remaining four songs are new to the show: Eddie Murphy's "Party All the Time" sung by Paltrow; Oh Honey's "Be Okay" performed by Michele and Naya Rivera; "I Am Changing" from the musical Dreamgirls featuring Colfer and Riley; and Pink featuring Nate Ruess's "Just Give Me a Reason" sung by Salling and Agron. A seventh song, Bonnie Tyler's "Total Eclipse of the Heart", which was to be sung by Chenoweth and Morrison, was cut from the episode, although it is included on the album.
